The fuel injectors are supplied with fuel oil through pipes
(bottom manifold) cast in several places in the side of
connected to the fuel inlet manifold. Excess fuel oil is
the cylinder head.
returned to the fuel tank from the fuel injectors through
pipes connected to the fuel outlet manifold.
The fuel manifold connectors are assembled to the
integral fuel manifold cylinder head, using special steel
The fuel inlet and outlet manifolds are an integral part of
sealing washers, and tightened to 40-45 Ib-ft (5461 Nm)
the current cylinder heads (Fig. 1). Since there are inlet
and outlet passages provided opposite each injector
A special fitting with a restricted opening is used in the
position in the side of the head as well as at each end,
fuel outlet manifold to maintain the proper pressure
greater flexibility is permitted in the installation of the
within the fuel system. Refer to Page 10-9-1 for the size
fuel lines to the fuel manifolds. The fuel passages are
of restriction used.
